ward direction as is der applving dev have been genera heretorore. i

s the present invention the tip" or nozzle is so formed that the powderis directed in "iective manner rear war 1 or both rearv. ardly an:forwardly; the direction of the rearward discharge being brought aboutby the provision in the rearend of thetip of a cavity into which all, ora portion of the powder pas inc; along the stem is discl'iarged. if devl s to be used for the rearwarrr discharge of powder only all the powderpassing along the stem enters the cavity and is deflected roarwardly andoutwardly. On the other hand, if the device is to be used to discha gethe powder both forwardly and rearwardly the tip will be provided withtwo cavities. one like that above described, and one at the forward endof the tip and provided with outlet openings in which event part of thepowder will enter one cavity and part the other.

The invention may be'further briefly summarized as consisting of certainnovel details of construction and combinations and arrangements of partswhich will be described inthe specification and set forth in theappended claims.

in the accompanying sheet of drawings Fig. 1 is a side view of acomplete powder applying device with parts in section, the or nozzlenere shown being utilized for the disclr e of powd. 1' both forwardlyand rearwardly. Fig. 2is a side view with the tip in section showing thestem and tip only. the tip here shown being for the rear ward dischargeof the powder.

In this instance the device consists of a bulb preferably formed ofrubber and connected to a receptacle 11 adapted to contain the powder,or other material to be tip discharged to treat the affected member;the.

material being indicated at 12. Connected Serial No. 493,844.

forward endof the receptacle 11 by to the HPHDS a plug 13 of rubber orother su1table material is a stenild to the forward end of which myin'iproved tip or nozzle is attached. In Fig. 1 the tip is designated bythe reference character 15, and inFig. 2

it isdesignated by the reference character 16; the tip. in the latterfigure being con nected to thestem 1'7 which corresponds to the stein 1dof Fig. 1.

is quite immaterial in what length, .or shape the stem is formed. .Forcertain purposes it will be short, and for certainother purposes it willbe relatively long. In some instances itwill straight as shown in 1, andin otherinstances it will be curved as shown in Fig. 2. Likewise, thesize of the tip 15 or 16 will depend upon the purpose for which thepowder applying device is to be used as is obvious.

Referring first to Fig. 2 which shows the tip for discharging the powderin a rearward direction only, it will be observed that this stem isscrewed into a threaded portionof the tip 16, the front part of which isimpe'r'forate, Likewise, it will be observed that the rear end of thetip is provided with a rearwrdly facing cavity 18 which is open at therear and provided with a somewhat tapered, or beveled wall. In orderthat the powder may be discharged from the stem into this cavity'thestem is provided near the forward or closed end of the cavity with aseries of small outlet openings indicated at 19., I

It will be observed that with a stemand tip arranged and constructed asshown in Fig. 2 the powder will leave the stem by way of the smallopenings 19 and be discharged into the rearwardly facing cavity 18from'which it will be discharged rearwardly, or rearwardly andoutwardly.

It is the provision of this rearwardly fac ing cavity with the outletopenings 19 in the stem which constitutes the principal feature of theinvention whether or not this cavity has associated with it a cavity atthe front end of the nozzle for the simultaneous discharge of the powderin a forward direction.

In Fig. 1 the tip 15 has a rearwardlycfacing cavity 18 and small outletopenings 19 precisely as shown in Fig. 2, but in addition it is providedwith a front cavity having forwardly facing discharge openings 21.

III)

In this instance the threaded end of the stem 14: is screwed into anopening formed in the equivalent of a bridge or partition 22 separatingthe front and rear cavities. l/Vhen this tip is employed part of thepowder passes through the openings 19 into the rear cavity and isdischarged in a rearward direction as in the first instance, and partpasses straight through the stem to the front cavity and from thiscavity is discharged from the tip in a forward, or forward and outwarddirection.

Although the device constructed as shown in Figs. 1 and 2 has proved bypractice to be very efiicient, and although I prefer that the tip beconstructed as shown in Figs. 1 and 2 I do not wish to be confined tothe precise details shown and aim in my claims to cover allmodifications which do not involve a departure from the spirit and scopeof my invention as set forth in the appended claims.

Having thus described what I claim, is:

1. A powder-applying device for medicinal purposes comprising a stem anda tip my invention 5 111g rearwardly of the point of attachment, arearwardly facing open ended cavity, and forwardly of the point ofattachment hav ing a front cavity, the stem having openingscommunicating with the rear cavity and the forward cavity havingdivergent forwardly directed discharge openings lead ing therefrom. I

2. A powder applying device comprising a bulb, a receptacle for powderconnected to the bulb, a delivery stem connected to the receptacle, anda tip carried by the stem,

said stem being connected to an inter-medial ate part of the tip, thelatter having a rearwardly facing open ended cavity for the rearwarddischarge of the powder, and having at the front forwardly of the stem asecond cavity with divergent forwardly directed discharge openingsleading therefrom, said stein having lateral discharge openings leadinginto said rearwardly facing cavity.

In testimony whereof, I hereunto my signature.
